Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAF94124 is determined by the following critical parameters:

Termination Compatibility: The RP-SMA Male connector is the primary mechanical and electrical interface requirement. All substitute parts must feature identical RP-SMA Male termination to ensure direct compatibility without adapter components.

Frequency Band Coverage: The MAF94124 supports 802.11a/b/g standards. Substitute parts must operate within the frequency ranges encompassing 2.4GHz and 5GHz bands to maintain functional equivalence for wireless LAN applications.

Connector Type and Gender: RP-SMA Male termination is non-negotiable for direct replacement without mechanical modification.

Regulatory Compliance: ECCN classification 5A991G must be maintained for export and supply chain continuity.

Environmental Rating: Moisture Sensitivity Level 1 (Unlimited) establishes the baseline environmental tolerance requirement.
